Abstract
Description
Technical Field
[0001] This utility model relates to the field of broad bean paste technology, and in particular to a cleaning device for making broad bean paste koji. Background Technology
[0002] Chinese utility model patent CN202420374411.6 discloses a cleaning device for making fermented soybean paste koji. The device includes a conveying mechanism for automatically conveying and placing the koji-making trays horizontally; a cleaning mechanism rotatably mounted within the conveying mechanism to clean the side of the tray containing the material; a spraying mechanism mounted on the conveying mechanism at both ends of the cleaning mechanism to rinse the side of the tray containing the material; and a guide hood mounted on the conveying mechanism to direct water sprayed by the spraying mechanism to the cleaning mechanism and the back of the tray containing the material. This cleaning device is used to clean the koji-making trays. The conveying and spraying mechanisms facilitate automated cleaning, while the cleaning mechanism ensures high-quality cleaning.

[0026] Please see Figures 1 to 4 The cleaning device for making fermented soybean paste in this embodiment includes a box 1. The top of the box 1 is provided with two drive wheels 4, which are arranged left and right. A drive belt 5 is provided between the two drive wheels 4. The two drive wheels 4 are connected by the drive belt 5. Several L-shaped buckles 6 are fixedly connected to the outer surface of the drive belt 5. The several L-shaped buckles 6 are made of rubber and have elasticity.
[0027] A rotating shaft is fixedly connected to the right center of each of the two transmission wheels 4. A motor 14 is provided on the right side of each of the two transmission wheels 4. The power output shafts of the two motors 14 are fixedly connected to the right end of the adjacent rotating shaft. A connecting rod 3 is fixedly connected to the side of each of the two motors 14 away from the center of the housing 1. Fixing plates 2 are fixedly connected to the front and rear sides of the housing 1. The other ends of the two connecting rods 3 are movably connected to the adjacent fixing plates 2 respectively. The rear end of the connecting rod 3 located on the rear side passes through the side wall of the rear fixing plate 2. A servo motor 8 is fixedly connected to the rear side of the fixing plate 2 located on the rear side. The power output shaft of the servo motor 8 is fixedly connected to the rear end of the connecting rod 3. Spray nozzles 13 are provided on the top of the housing 1 near the left and right sides. Hard water pipes 16 are inserted into the clean water inlets of the two spray nozzles 13. The bottom end of the hard water pipe 16 passes through... The top of the housing 1 extends into the inner cavity of the housing 1. A water tank 15 is fitted to the bottom of the inner cavity of the housing 1 near the left and right sides. The bottom ends of two hard water pipes 16 are inserted into the adjacent water tanks 15. A cleaning shaft 12 is provided between the two nozzles 13. Several cleaning brushes 7 are fixedly connected to the outer wall of the cleaning shaft 12. Baffles 17 are fixedly connected to the top of the housing 1 near the four corners. A drive shaft 11 passes through the center of the cleaning shaft 12 and is fixedly connected to it. The left and right ends of the drive shaft 11 are movably connected to the baffles 17 on the left and right sides respectively. A micro drive motor 10 is fixedly connected to the right side of the baffle 17 on the right side. The power output shaft of the micro drive motor 10 is fixedly connected to the right end of the drive shaft 11. Several drainage holes 9 are opened on the top of the housing 1 near the left and right sides.
[0028] Working principle: In use, the operator first fixes the koji-making tray between the transmission belt 5 and the L-shaped clips 6 using two L-shaped clips 6 on the left and right. Then, the operator starts the nozzle 13 on the rear side to rinse one side of the koji-making tray for the first time. The koji-making tray is moved by the transmission belt 5. Then, the micro drive motor 10 is started. The power output shaft of the micro drive motor 10 drives the transmission shaft 11 to rotate. The transmission shaft 11 drives several cleaning brushes 7 through the cleaning shaft 12 to scrape and sweep the beans that cannot be rinsed off the koji-making tray. Then, the operator starts the nozzle 13 on the front side to rinse the koji-making tray for the second time. The rinsed koji-making tray will move to the top of the transmission belt 5. Then, the operator removes the koji-making tray, adjusts its direction, and exposes the side of the koji-making tray that has not been cleaned. Then, the above cleaning steps are repeated to complete the cleaning operation on the other side of the koji-making tray.
[0029] At the same time, the servo motor 8 can be started. The forward and reverse rotation of the servo motor 8 can adjust the angle of the entire transmission belt 5, which makes it easier to adjust the angle of the koji-making disc and to clean its corners, thus improving the cleaning effect.
[0030] Meanwhile, the water generated during the cleaning process flows into the interior of the box 1 through the drain hole 9 for collection. The baffle 17 prevents water from splashing everywhere during the rinsing process, thus optimizing the working environment.
[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
